The 24 V output is not suited to supply external safety circuits because an external voltage source is
necessary to comply with the applicable standards. If the safety function (STO) is not required, this voltage
is only used to bridge the pins 1 and 3.
Specification of terminal connections
▶
Conductor cross-section solid/stranded: 0.14 to 1.5 mm²
▶
Tightening torque: 0.22 to 0.25 Nm
Note
The power supply unit is only activated when SAFEA and SAFEB are connected. If the
safety function (STO) is not required, pin 1 and pin 3 must be bridged to pin 6.
